SIDE BEARING FOR CARS.

SPECIFICATION forming part of Letters Patent No. 791,760, dated June 6, 1905.

Appumion flied May 20,1904. seria No. 208.849.

To all whom it may concern,.-

Be it known thatI, ROBERT L. ELLERY, a citil zen ofthe United States, residing at Portsmouth, in the county of Rockingham and State of New Hampshira. have invented new and useful Improvements in Side Bearings for Cars', of which the following is a specification. This invention relates to a sliding side bearing for cars so constructed that the sliding surfaces of the two main parts of said bearing-viz., the part attached to the car and the partattached tothe car-truck-shall be and remain in contact with each other in all .the varying positions which said VcarV and truck may assume with relation to each other.

The invention consists in a side bearing for car-trucks comprising a base-plate and a top plate adapted to slide one upon the other, said top plate formed in two parts-wiz., va bolster-plate and a slide-plate constructed to slide vertically upon said bolster-plate.

The invention again consists in certain improved details of construction set forth in the following specification and particularly pointed out in the claims thereof. Referring to the drawings, Figure 1 is a plan view of my improved side bearing for cars, together with a portion of a car-bolster and truck-bolster to which said side bearing is attached. Fig. 2 is a section taken on line 2 2 of Fig. 1. Fig. 3 is a section taken on line 3 3 of Fig. 1 looking toward the rightin said figure.

Like numerals referto like parts throughout the several views of the drawings. i

In the drawings, 10 is a base-plate, which is fastened by bolts 11 to a truckbolster 12. The upper surface of said base-plate-lO is in sliding contact with a top plate 13, said top -plate formed in two parts-viz., a bolsterplate 14, adapted to be fastened to a car-body and extending longitudinally thereof, and a slide-platel, constructed to slide vertically on said bolster-plate. The slide-plate 15 is provided with vertical flanges 16 16, which project into grooves or Ways 17, formed in opposite ends, respectively, of the bolsterplate 14, which isrigidly fastened to a carbolster 18 by screws or bolts 19. The bol- Ster-plate 14 is provided with recesses 20 20 vlower vface of said to receive springs 21 21, which project downwardly therefrom, with their lower ends resting uponvthe top of the slide-plate 15. Projections 22-are provided upon the upper face of said slide-plate, which project into the lower ends of said springs 21 in order to guide and centrally locate the same. It will be under-l stood that the slide-plate 15 and bolster-plate 14 form together a top plate 13, the action of the springs 21 being to force the slide-plate 15,

downwardly away from the bolsterplate 14 and in contact with the base-plate 10.

.When the car-body is raised from' the truck in order to prevent the slide-plate 15 from dropping off of the bolster-plate 14, screwthreaded pins 23 are provided Which are fast to said car-bolster upon opposite sides, respectively, of the ways 17 and project through vertical slots 24, provided in the flanges 16 of the slide-plate 15.

VThe operation of the device hereinbefore described is as follows: The base-plate 10 being fastened to the truck-bolster 12 and the bolster-plate 14 rigidly fastened to the carbolster 18, while the slide-plate 15 is interposed between said base-plate 10 and bolsterplate 14, free to slide vertically upon said bolster-plate and horizontally upon said baseplate, it will be seen'that'as the truck turns upon'its pivotal center the upper surface of the base-plate will slide horizontally along the "slide=plateround a curve and rock laterally the springs 21 will yield'to allow the slide-plate 15 to rise or fall, as may be necessary in order to keep the sliding under face of said slide-plate incontact with the upper face of said base-plate.

One of the principal advantages derived from the use of my improved side bearing consists in the fact that in the lateral rocking of the car relatively to the truck the sliding surfaces of the top plate and base-plate, respectively, will be always held in contact one with the other, so that there will be no hammering or`oth'er undesirable -action between the top plate and base-plate. It will be understood that the springs interposed between the bolster-plate and the slide-plate actas cushions to prevent any hammeringjbetween the dilferent parts of the side bearing form- As the cars` ing a yielding support for the side of the car in a structure, the different parts of which are adapted to slideboth horizontally and vertically with relation to each other.

Another advantage derived from my improved side bearing is that the same may be introduced on cars asnow manufactured in place of the side bearings in ordinary use.

Having thus described my invention, what I claim, and desire by Letters Patent to secure, is-

1. A side bearing for car-trucks comprising in its construction a base-plate 10 and a top plate 13, adapted to slide one upon the other, said top plate formed in two parts, viz., a bolster-plate 14 and slide-plate 15 constructed to slide vertically upon said bolster-plate.

2. A side bearing for car-trucks comprising in its construction a base-plate 10 and a top plate 13, adapted to slide one upon the other, said top plate formed in two parts, a bolsterplate 14 and a slide-plate 15 constructed to slide vertically upon said bolster-plate, and springs Q1 interposed between said slide-plate 15 and bolster-plate 14.

3. A side bearing for car-trucks comprising in its construction a base-plate 10 adapted to be fastened to a truck and a top plate 13, said plates adapted to slide one upon the other, said top plate formed in two parts, viz., a bolsterplate 14 adapted to be fastened to a car-body, and a slide-plate 15 constructed to slide vertically on said bolster-plate.
